In a binary tree with a series of insertions leading to an imbalance, describe how you would perform successive right and left rotations.
💡 Hint: Map out the tree after several insertions to visualize needed rotations.
Explain the consequences of failing to maintain height information in nodes after rotations.
💡 Hint: Consider how balancing impacts retrieval performance.
